Abstract
Appareil (20, 120) servant à former une feuille de verre chauffé (G) et comprenant un moule à vide (22, 22a, 122, 122a) ayant toute une surface (24, 24a, 124, 124a) contre laquelle un moule périphérique (26, 26a, 126, 126a) vient presser la périphérie de la feuille de verre. Cet appareil comprend au moins un réservoir à vide (32, 33) qui communique avec l'intérieur de la périphérie soudée de la feuille de verre pour donner à la feuille de verre la forme de la surface du moule à vide. Les vannes (38) d'un système à vide (28) fonctionnent préférablement pour produire l'impulsion de vide en deux phases avec une quantité initiale limitée de vide et une quantité supérieure de vide complémentaire qui communiquent d'abord avec un premier réservoir à vide (32) puis avec un second réservoir à vide (33). Dans différents modes de réalisation du moule à vide, la surface du moule à vide est orientée vers le haut et vers le bas avec des formes convexe et concave. Des formes de feuille de verre comprenant des éléments rectilignes tels que des raccords cylindriques et coniques, ainsi que des formes comprenant des courbures dans les directions transversales et des courbures inverses, peuvent être efficacement produites à l'aide de ce procédé de formage à impulsions de vide.
